Abstract
A compact fiber rotator has a guiding and support device (2) which comprises suction channels (17) formed in the angle of two blocks (3, 5), and a rotation device (32) which is attachable to the guide device (2) and comprises a house (33), a rotating toothed wheel part (37), a platform (31) attached thereto and an electric step motor (43). The fiber (1) is secured on the platform (31) by means of a standard fiber retainer (61) which is retained at the platform (31) by means of magnets (29), the rotating part (37) being located between the support (2) and the retainer (61). The suction channels (17) of the support device can be provided with a suitably low negative pressure, so that the fiber which is to be rotated and welded can be retained satisfactorily but still may be rotated against smooth surfaces of the angle of the blocks (3, 5). The toothed wheel part (37) of the rotator device is provided with a slot (45) between two gear teeth (39), in which the fiber (1) which is to be rotated and welded is placed. The electrical step motor (43) is on its output shaft provided with a gear pinion (41) which is engaged with the teeth of the toothed wheel part (39), so that the motor (43) can be controlled to rotate the fiber (1) to a desired angular position.
